Nuclear vs SciQuiz
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Nuclear
Explore the quantum world and learn about chemical elements by building atoms. This app visually models interactive atoms, allowing you to add or subtract subatomic particles to construct stable elements and unlock them on the periodic table.
- Interactive 3D atom visualization
- Build chemical elements by adding/subtracting particles
- Unlock elements on the periodic table
- Explore atomic decay of isotopes
- Learn about matter at the atomic scale

*** Brought to you by the team behind the internationally acclaimed educational star gazing app - Star Chart *** Dare you enter the quantum world of Nuclear? Where things are not just stranger than you might imagine, but stranger than you can imagine! Witness the interplay of energies and physics at the tiniest of scales as you learn to play, discover and explore the chemical elements at the atomic level. Nuclear is a high tech educational application that dynamically models an interactive atom in a beautiful and intuitive way. In Nuclear, you get to build all the elements of the periodic table via a simple mechanic of adding and subtracting the atomic building blocks of neutrons, protons and electrons. The goal of the app is to let you learn about each of the elements of the periodic table by constructing a stable version of that element. Once a stable element has been created, it is unlocked in the periodic table. Can you create and unlock them all? This app has been designed for all types of users: from children interested in learning through play about what matter is made of and how it works, to teachers looking for an intuitive and exciting way to help educate others on chemical elements. Nuclear lets you: * Learn about the atom through this stunning 3D visualisation. * Explore the effects of manipulating matter at the atomic level. * Add or subtract protons, electrons or neutrons to create virtually any base chemical element. * Create and watch as unstable isotopes decay into more stable elements. * Through tactile exploration grasp an understanding of what we and everything around us is made of. - Please note the initial app allows you to create and unlock the first 54 elements for free. The remaining elements can be unlocked via a small in-app purchase. Nuclear is continually being developed, so please feel free to let us know your thoughts and feedback. We will endeavour to expand and improve Nuclear, incorporating customer feedback wherever possible.

Verdict
The clearest difference is in-app purchases: SciQuiz at none against Nuclear's 3. SciQuiz also leads on rating (4.6 vs 4.2). Nuclear's advantage is ads (none vs shown) and ratings volume (302 vs 53). On price, review sentiment, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Nuclear sells 3 one-off in-app purchases. SciQuiz asks for nothing beyond the download.
SciQuiz holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Nuclear has 302 ratings behind it against 53, so its average is the more settled of the two. Written reviews complicate that: 69% of Nuclear's written reviews are positive against 67% of SciQuiz's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 20, 2026 and October 15, 2026 respectively.
